GQNNECTOR'.

T0 all wlwm z't may concern:

. Be it known that I, GEORGE W. KATZUNG, a eitizen of the United States, tesiding at Pit;tsfield, in the county of Berkshire, State of Massatzhusetts, have invented Certain new and useful Improvements in Coi mectors of which the following is aspecificzition.

My invention relates tothe manufacture 0f a connector for electrical conduetors and has for its object to produce a sifnple, cheap and eflective device 0f this charabter.

More particularly my invention relates to a soeket for a connecting plug for connecting and disconnecting a heating device 01' the like with a snpply circuit.

F01 a more complete understanding of my invention reference may be had t0 the accompanying drawing in 'which Figure 1 is a plan view 0f a metal blank from whieh a Socket embodying my invention may be formed; Fig. 2 is a perspeetive view of a socket formed from the blank cf Fig. l; a1id Fig. .3 illustrates the sooket of Fig. 2 in position in a connecting' plug.'

Referring DOW to the drawing and first t0 Fig. 1, 10 is an elongated metal blank from which the soeket shown in F'ig. 2 is formed. Openings 11 are formed in the blank wl1'ich, when the blank is folded on the transverse medial line ofthe blank as shown in Fig. 2,

register with eaeh other and oonstitute anopening f0r the reception of a binding post. Spring the blank, extending toward the transverse medial line of the blank as shown in Figs. 1 and 2 particularly and are preferably tapered as at 13. 'Preferably the fingers are punched 0ut 0f the metal, and Whe'n this is done a narrow section of metal should be removed from the edge 0f the finger so as to form an opening 14 around the spring finger andperrnit free movement of-the finger in the opening from which it is formed. It Will be understood, however, that a secition 0f the metal plate may, if desired, be stamped from the plate around the finger be formed. .In cas e the finger is formed by being punched from the metal, then When the section of metal has been remoVed from the edge of the fingen, it is bent back into position m the plane of the plate. The ends of the blank are then stamped into a suitable form for the socket, preferably semi-cylindrical as sho wn in Eig.

fingers 12 are formed at either end of Patented Feb. 24 1920.

Appli cation filed December 4, 1916. Serial N0. 134,884,

2,and the two pzirts of the blank are bent at 15 to form the sQoket A, The spring fingers- 12 are then sp'rung inwardly slightly, o1 given an inward. Set, so as to exert a pressure against the pin terminals Whieh are received in the soeket.

In Fi 3 I have shown one of the sockets embodymg my invehtion in position within the conneeting plug B. This plug is made 0:E

tw o sections 16and 17 in a manner Well known in the artQ The sections are provided with openings 19 in which the sockets are received and are forrned at their ends with openings 20 to accommodatethe pin terminals which enga,ge the Sockets. The conductor 21 is connected to the socket by a binding post 22 in the usual malnner.

It Will be apparent that any am that may be formed between the terminal am]. the s0cket will be formed at the end 0f the socket and. that the spring fingers which canstitute the working arts of the soeket will be free from the'pitting that commonly res'ults from arcing.

In accordance with the provisions of the patent statutes, I have described the principle of operation of'my invention, together with the apparatus which I no wconsiderto represent the best desire t0 have it understood that the apparatus shown is'only illustrative, an that the invention can be carried out by other ineans.

What'1 claim as new and desire to secure by Letters Patent o-f the United States, is:

1. The method cf making a inetal socket for a connector which consists in punching 'out spring fingers from a metal blank, removing a section of metal from the edges of' the fingers to permit free movement of the fingers relative to the blank, stamping the blank into a suitable form and bending the Same upon itself with the fingers sprung inwardly toward eaeh other.

2. A socket for a connector comprising a single pie'ce extending in the same direction from embodi'rnent ther'eof'; laut I piece of metal, the two halves of said the end of said connector at which the said two halves are joined, to receive the co-acting terminal between the two ends of said piece, each of said. halves being provided with a resilient finger extending toward the opposite half to constitutei working surface s.

3. A socket for a eonnector compmsing a single piece'of metal, the two halves of said piece extending in the same direction frpm the end 01 said connector at Which the said two halves are joined, to receive the co-act ing terminal between the two ends 015 said piece, eatch 01 said halves being provided -With a resilient finger integral therewith and .extending toward the opposite half and tovvard sz'zid end of the connector t0 constitute working surfaces remote from the end of the socket receiving the co-'acting termi- 10 nal.

In witness vvhereof, I have hereunto my band this 28th day of Nov. 1916.

GEORGE W. KATZUNG.
